What do you think of the theory that homosexuality is genetically similar to an addiction, where if exposed to certain environmental factors, they will become homosexual?
     Les Biesecker, M.D.: Researching the clinical and molecular delineation of human malformation syndromes. Human behaviors are some of the most complex traits a geneticist could try to tackle. All traits are a complex mix of genes and environment and behavior is no exception. Sexual preference, addiction, depression, risk taking, etc. will all take a while to work out. I think it is highly likely that both genes and environment have an important role.
